Özet
In this study, dielectric properties of sulfonated poly(ether ether ketone) (SPEEK) solid polymer electrolytes (SPEs) containing room-temperature molten salt, 1-ethyl-3-methylimidazolium tetrafluoroborate were investigated. Additionally, the effects of ionic liquid (IL) addition on the thermomechanical properties and the micro-structure of composite electrolytes (SPEEK-30 × 1IM and SPEEK-30 × 2IM) were studied. The characteristics of the SPEs were investigated by FTIR, SEM, TGA, DSC and DMA measurements. FTIR analysis confirmed the success of the sulfonation process and IL/sulfonated polymer interactions. IL addition caused changes in the crystalline structure and surface morphology of the SPEs. It was observed that SPEEK-30 × 1IM and SPEEK-30 × 2IM electrolytes have lower glass transition temperatures (Tg) and crystallinity than that of pure SPEEK-30. Due to the amorphous character formed …
